Energy
The energy industry is changing rapidly, as is the emergence of waste recovery sectors (methanization, thermal recovery, etc.).

Meanwhile, conventional sector’s (thermal and nuclear energy) must maintain production at their sites where the use of water is essential:
- Nuclear energy: cooling facilities, safety backup and storage, firefighting circuits, sanitation facilities
- Thermal energy: process water, cooling, flue gas cleaning, fire circuits...

Each use requires a specific water quality. Water treatment is necessary, whether to supply processes or to discharge it into the environment.
We help energy producers to treat their water, whether on a permanent basis or occasional interventions (such as a shutdown for maintenance).
Specific cases

Fluoride treatment solution:
- Physical and chemical treatment by coagulation and flocculation
- Separation by clarification and pH regulation
Parameters | Input | Discharge |
Fluorides – mg/l | 290 | 60 |
SM - mg/l | 12,9 | 6,5 - 8,5 |
Flow rate - m3/hr | 3 |
